Explanation / Answer
JDemoFrameThatCloses.java
Did changes in code to display all the orders related data.
Kindly go through the ITEM-01,02,03,04 description and code (which I included) to get better idea.
import java.text.DecimalFormat;
import javax.swing.JOptionPane;
/*****
* @author kishore
*
*
* ITEM-01----Declared a string buffer variable to store all the orders related data on addition of each order
*
* ITEM-02---This line of code actually stores each order related data in string buffer
*
* ITEM-03----Added a line of code to remove all the content from string buffer once user clicks on clear button, to clear all the previous orders data
*
*ITEM-04---This line is changed to display all orders related data (available in string buffer) instead of displaying last order data
